Homework Statement A uniform solid sphere,rolls without slipping on a horizontal surface with an angular velocity \omega,meets a rough inclined plane of incination 60(degrees).The sphere starts pure rolling up the plane with an angular velocity.Find the new angular velocity . Homework...

I meant that A should not leave contact with the wall. Sorry for my english.

On the left side of block A there is a wall on the right side of A there is a spring attached to A and the other end of the spring is attached to B.Now B is pushed against the wall so that the spring compresses. I think now it is more clear.

Homework Statement A block A has mass =2kg and is attached to a spring of spring constant=40N/m .Another block of mass 4kg is pressed against A so that the spring is compresses by a distance 'd' .Then find the maximum value of 'd' for which on release of the B does not lose contact from the...

From the sum and the product rule of the quadratic equation we can easily get 12-5(y+z)+2yz>0.. and from this one we can get some conditions..

For brainy students!

If a(12a+5b+2c)>0 and the equation ax^2+bx+c=0 has roots y and z , then find out the range of the roots of the equation ...
